Clearly “Post the fucking article” is not interchangeable with “Post the article which is fucking.”

THE STRANGE EMOTIONAL power of swearing--as well as the presence of linguistic taboos in all cultures-- suggests that taboo words tap into deep and ancient parts of the brain. In general, words have not just a denotation but a connotation: an emotional coloring distinct from what the word literally refers to, as in principled versus stubborn and slender versus scrawny. The difference between a taboo word and its genteel synonyms, such as shit and feces, cunt and vagina, or fucking and making love, is an extreme example of the distinction. Curses provoke a different response than their synonyms in part because connotations and denotations are stored in different parts of the brain.

Choice fucking read, imo.
